To all whom it may concern.-

Be it'ltuown that I,W1LHELM SONNENBERG, ol' Winona, in the county of\Vinonaand State of Minnesota, have invented a new and ImprovedBreech-Loading Fire-Arm, of which the following is a full, clear, andexact description.

The object of my invention is to provide a new and improvedbrecclrloatling tire arm, in which the hammers and triggers aresctantoinatically and lockcdin position when the ban rel is opened forloadin The invention consists of a device for locking the barrel on andunlocking it from the stock, means for setting the hammers and triggerswhen bpening the barrel, and a device for locking the triggersautomatically by the device for locking the barrel on or unlocking itfrom the stock. 7

Refercnce is to be hadto the accompanying drawings, forming a part ofthis specification, in which similar letters of reiiztence indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal central section of my improvement in a closedposition. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinalsection of the same,showing the barrel open. Fig. 4 is a vertical crosssection of the same on the line 00 a: of Fig. 3. Fl". 5 is an invertedsectional plan view of part of the same on the line 7; of Fig. 3. Fig. 6is aplan and a side view of the bar or rod operating the hammers, andFig. 7 is an inverted plan View of a locking device for thebreeclrblock.

The single or double barrel A is provided on its under side with thetongue 13, having; a half-round notcigli, engaging the pivot-pin (3,held in the frontend of the stock 1), and on which swings the said barreA. On the nadcr side of the barrel A is also held a removable plate,13', which swings with the barrel A on the pivot O and operates themechanism E (see Fig. (5) for setting the hammers F. p The mechanism Econsists of a bearing, E, i'ulcrumed on the pivot O, and having a pin, Eprojecting loosely into a horizontal aperture formed in the plate B, andthe said arm E is also provided with a lug, E, operating on a rod orbar, E, adapted to slide in suitable bearings formed in the stock D. Thein nor end of the rod 15* is provided with'a notch, E engaging ashoulder or lug, F", on a hammer, F, which is of the usual construction.

The hammer-lever G engages at one end, in

the usual manner, with the said hammer F,.

and its other end projects over the respective trigger or triggers H,which set off the ham mcr or hammers F. The trigger or triggers H can belocked in position by a bar,

adapted to slide in hearings on the bottom plate, D", of the'stock D,and engaging with its front end a notch. 11, formed on the tops of thesaid triggers H.

The rear end of the sliding bar I connects by the lever, I with theirodI", held in suitable bearings on the" under side of the top plate, D,olthe stock I), and the said rod is provided with a' knob, 1", extendingthrough a slot in the top plate, I). The spring'l, secured by one end tothe bottom plateDflot' the stock D, engages with its otheriree endprojection. F, on the lever 1, so as to hold the latter in whateverposition it is in.

The inner end of the barrel A is provided in its middle with aprojection, A, having a square aperture, A", into which passes thescgmcntai arm J, tulcrumcd on the shaft K. adapted to turn in the stockI), and provided on its Upper outer end with a hand lever, K, swingingon the top plate, D, of the stock D, and provided with a collar, K",having a downwardlycxteinling lug, K operatii'lg on the lever L, pivotedto the under side of the top plate, I), and operating against the springL. The outer end of the lever L is connected by a link, J, with thesegmental arm J.

On the lower end of the shaft K is secured a disk, N, on the under sideof which rests one end of the arm t) of the L-shaped arm 0, which hasitsother arm, 0, extending upward, and is pressed against the inner end ofthe tongue B by a spiraljs'pring, P. The disk It has a notch, hi, intowhich drops the end of the arm 0 when the-shaft K is turned so that thespring I forces the said arm 0 upward.

The operation is as follows: \Vhen. the tirearm is in a closed position,as shown in Fig. 1, then the'barrel A is held in a locked position onthe stock D by the segmental arm J, engaging the aperture A in theprojection A of the barrel A. I The operator, by pressing thetrig gersII, causes the hannn'rs' F to strike the tiring-pin Qin thensual manner.The lug F of the hammer F is now engaged with the notch of the rod E,and when the operator now desires to open the barrel A for reloading heswings the hand -lever K to the right, whereby the lugK eauses the leverL to swing toward the rear, and the latter, by means of thelink J causesthe segmental arm J to swing in the same direction, sothat the latterdisengages from the projection A of the barrel A. At the same time theturning of the shaft K brings the notch N in the disk N opposite the arm0' of the L-shaped arm 0 and the latter is pressed upward by the springP,,thus engaging the notch N, and thereby holding the shaft K and itsconnection in a locked position. \Vhen the lever L swings toward therear, it comes in contact with the'bar I and causes the same to slide"in the same direction, so that the bar I is moved forward and overthe-notches H inthc top of the triggers H, sothat thclatter are held inalocked position. The operator, by pressing on the outer part of thebarrel A, causes the latter to'swing on its pivot ,G into the positionshown in Fig. 3, thus enablinghim to reload thebarrel A. This swingingmotion of the barrel A imparts a rearward motion to the rod E by the armE being turned on the pivot O by the swinging plate. B. This slidingmotion of the rod or bar E imparts aswinging motion to the hammer F,which :is thusreset read'y for action. \Vhen the operator noweloscs thebarrel A, thenthe upwardly-projeeting arm. 0" of the L; shaped lever Ois pressed downward by the inner edge of the tongue 13, so that the. armOjs disexr gaged from the notch N of the disk N, and the spring L,pressing on the lever L, now causes the. shaft K and its hand-lever K toturn to their former positions, and the segmental arm J is again swunginto the aperture A of the lever A, thus locking the barrel A in placeon the stock I). if theoperator now desires to tire, he has to ,move theknob 1 forward, so that the sliding bar I' is disengaged from thetriggers I I.

Having thus" fully described my invention,

I claim as'new and desire to secure by Letters,
